Study Describes Long-Term Outcomes Of Pediatric Pulmonary Embolism
Up to nearly one-third of pediatric patients with thromboembolic pulmonary embolism (PE) experienced abnormal functioning, which was more common among those with underlying conditions, according to the results of a cohort study published in the journal Blood. However, post-PE syndrome was uncommon and rarely persisted.
The study analyzed data from 150 patients aged 0 to 18 in the Thrombosis Database at SickKids who were diagnosed with acute PE and who survived for at least 6 months after diagnosis. The median follow-up was 521 days with a median of 3 outpatient visits.
At baseline, the median age at diagnosis was 16 years and 47% of patients were male. There were 61% of patients with an underlying condition, which included autoimmune disease among 22%, cancer among 13%, infectious disease among 5%, and cardiac disease among 5%. There were 17% of patients with more than 1 comorbidity.
Hospital acquired PE was more common among patients with an underlying condition, with a rate of 63% compared with 29% of patients without an underlying condition (P <.001). In contrast, oral contraceptive use was present among 78% of patients without an underlying condition compared with 30% with a condition (P <.001).
The most common treatment was anticoagulation, which was used among 82% and 81% of patients with or without an underlying condition, respectively. Anticoagulation plus thrombolysis/thrombectomy was used in 13% and 19% of patients, respectively.
The PE was not resolved at follow-up among 32% of patients with an underlying condition and 26% of patients without (P =.47). Recurrence was more common among patients with an underlying condition at 13% compared with 1.7% among patients without (P =.016). The rate of death was 6.5% and 1.7%, respectively (P =.25).
Patients with or without an underlying condition demonstrated transient abnormalities after PE, which included dyspnea or increased work of breathing in 18% and 21% of patients, respectively (P =.84) and abnormal echocardiogram findings in 9.3% and 1.9%, respectively (P =.11).

Abnormal functional findings were seen in up to 20% to 30% of children diagnosed with thromboembolic PE, most commonly ventilatory impairments, impaired aerobic capacity, exertional dyspnea, and DLCO impairment.
The rates of chronic dyspnea were 7.6% and 5.2% in patients with or without an underlying condition, and the rates chronic abnormal echocardiogram findings was 5.8% and 1.9%, respectively. Chronic thromboembolic pulmonary hypertension and post-PE cardiac impairment each occurred in 1 patient with an underlying condition.
Post-PE functional impairment was evident among 9.7% of patients with an underlying condition and 7.1% without (P >.99). Patients with underlying conditions were more likely to demonstrate diffusing capacity of the lungs for carbon monoxide (DLCO; P =.001) and ventilatory (P =.049) impairments compared with patients without.
At follow-up, maximal oxygen consumption (VO2) and abnormal VO2 peak z score were higher among patients with underlying conditions (P =.042 and P =.040); however, there was no significant difference in percent peak heart rate, peak workload, peak oxygen saturation, or exercise desaturation.
"Abnormal functional findings were seen in up to 20% to 30% of children diagnosed with thromboembolic PE, most commonly ventilatory impairments, impaired aerobic capacity, exertional dyspnea, and DLCO impairment," the authors concluded in their report.

How Technology Is Bringing Cardiology, Cardiac Surgery Together
New technological developments in the cardiology field have increased collaboration to improve patient care, according to one cardiac surgeon.
Frank Fazzalari, MD, who is the chief of cardiothoracic surgery at Troy (Mich.) Beaumont Hospital, recently connected with Becker's on the state of the cardiac surgical and cardiology fields.
Note: Responses were lightly edited for clarity and length.
Question: What are the biggest challenges facing the cardiology and/or cardiac surgery field?
Dr. Frank Fazzalari: A lot of cardiac surgeons now are hospital-affiliated, with the majority of them probably as part of a hospital-employed medical group. That has happened over the past 15 years or so, which has led to there being very little purely private practice cardiac surgical groups left in the country. I think that's a little different in cardiology, but my guess is over time that they may experience the same sort of pressures as we have. I think that's one of the pressures that have caused cardiac surgeons now to be mostly somewhat financially affiliated with health systems.
The other pressure, I think that's more toward cardiology specifically, is the advent of freestanding cath labs. That's a new thing that's come up where groups or entities or cardiologists are able to have their own cath labs outside the hospital. So that gives them even more market power over hospital systems, which is a change in the market dynamics. That is a negative pressure on hospitals because they are potentially losing some of that revenue. The same things are happening in surgical subspecialties like general surgery and gastroenterology; a lot of those have been shifted out of the main hospital and into privately owned surgery centers. This is just kind of another example of that in the cardiology space. Obviously, that's a negative for the hospitals that lose out on that revenue and those patients.
Q: What is one positive trend you have seen in the industry?
FF: Advancements in technology, such as transcatheter aortic valve replacement, have further incentivized cardiologists and cardiac surgeons to work more closely together, which is a positive for patient care. Before TAVR, in the past the two specialties were relatively siloed, and now we're working much closer together. I think that's another benefit for patients because you know our goal is to take care of the patients. There's a lot more collegiality and working a lot better collaboratively with structural heart cardiologists, and I think it all came about through TAVR.
